Do Personal Reserves Effect Mastery Badges?

82nd_19D1P_D3, on Apr 17 2018 - 15:07, said: I am trying to get the mastery badge emblem on the KV-1S but seem to be having no luck. Last match I got 7 kills and 3 special medals with 1400 damage and only got a 1st class. Because mastery badges are based on XP I was wondering if I would have had a booster activate (like 100% XP) if it would have helped. Thanks.
